My invention consists in the use of a polisher made in two or more sections, and of any convenient material, and operated by a powerful spring, in suoli a manner that the article upon which the polishing is to be done is firmly held and compressed by the sections.

The machine is illustrated more in detail in the side View, Figure l, and in thesectional view, Fig. 2, in which the position of the sectional polisher is shown. Fig. 3 is a front view of one section of the polisher; Fig. 4, a side view of the same..

My machine consists of a hollow mandrel, A A, operated bythe pulley B. Upon one end, or in any other convenient position upon the mandrel, is placed one or more slotted hubs, into which is placed the sectional polishers O O, operated and compressed by the springs D l What I claim as my invention, and desire to secure by Letters Patent, is-

The revolving hollow mandrel A, provided with the sectional polishers O C, regulated by the springs D D, and operated substantially in the manner and for the purpose set forth.
